he will pay $31 in interest after 6 months so after 6 months he will pay $531
(40×5)+(2×5) so 40×5=200 and 2×5=10 so 200+10=210
The answer is 55.75! Trust me I took a test on this and its the right one.
You would be able to cut 144 pieces of wire from the spool because 270/1 7/8 (or 1.875) equals 144
Answer:
Let X the random variable that represent the number of emails from students the day before the midterm exam. For this case the best distribution for the random variable X is
The probability mass function for the random variable is given by:

The best answer for this case would be:
C. Poisson distribution
Step-by-step explanation:
Let X the random variable that represent the number of emails from students the day before the midterm exam. For this case the best distribution for the random variable X is
The probability mass function for the random variable is given by:
And f(x)=0 for other case.
For this distribution the expected value is the same parameter
And for this case we want to calculate this probability:

The best answer for this case would be:
C. Poisson distribution
